Tbh I doubt users would notice. If you have a USB cable near you, check if the USB A plug has a blue core, or you can count how many connections there are inside. If its not blue and has four connection (or five in the case of mini / micro versions), its USB 1.x/2.x. USB 3.0+ should be blue and has nine connections (except for USB C, which has 24). USB 1.x/2.x cables seem to be everywhere, at least where I live. And yes I’m saying 1.x/2.x because both use the same connectors and cables, with additions in 1.1 and 2.0 revised.
